By and large, MythTV logs only exist to figure out what happened after
the fact. If you're getting guide data, there is no real reason to go
worrying about things.
Second, you seem to be pulling days individually from DataDirect. Don't
do that. Add the '--dd-grab-all' option to the command you told
mythbackend to use for mythfilldatabase, and all 14 days of guide data
will be pulled in one large chunk. It's much easier on their servers,
and it ensures you always have good guide data, rather than the standard
method of only pulling the next and last days independently.
